Crucial's high-density DDR2 Very Low Profile (VLP) DIMMs are uniquely designed for today's blade server and network router technology, meeting the ATCA form factor guidelines and offering an optimized solution for today's server room needs. Compatible with existing RDIMM sockets, these modules significantly boost your overall telecom and networking capabilities by addressing the biggest design challenges in today's networking and server applications: space, speed, airflow, thermal power consumption, and more. That means your organization will reap the benefits of less motherboard space dedicated to DRAM, while improving airflow and reducing the power needed to cool you system. In addition, our VLP RDIMM modules are backwards-compatible with existing sockets, delivering immediate benefits without any product redesign.


Dual inline memory module (DIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold pins on the bottom of the DIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a DIMM are not connected to each other. 240-pin DIMMs are used to provide DDR2 SDRAM memory for desktop computers. DDR2 is a leading-edge generation of memory with an improved architecture that allows it to transmit data very fast.
